Determines whether a query should be logged. Reads the "db.log.slow_query_threshold" system property, which can be changed by the user at any time. If the value is zero, then all queries will be considered slow. If the value does not exist or is negative, then no queries will be considered slow. This value can be changed dynamically while the system is running. For example, "adb shell setprop db.log.slow_query_threshold 200" will log all queries that take 200ms or longer to run. @hide

Appends an SQL string to the given StringBuilder, including the opening and closing single quotes. Any single quotes internal to sqlString will be escaped. This method is deprecated because we want to encourage everyone to use the "?" binding form. However, when implementing a ContentProvider, one may want to add WHERE clauses that were not provided by the caller. Since "?" is a positional form, using it in this case could break the caller because the indexes would be shifted to accomodate the ContentProvider's internal bindings. In that case, it may be necessary to construct a WHERE clause manually. This method is useful for those cases. @param sb the StringBuilder that the SQL string will be appended to @param sqlString the raw string to be appended, which may contain single quotes
